RedSim eSIM Data Plans for Singapore

RedSim does not provide a true unlimited‑data eSIM for Singapore. All of its Singapore‑specific plans that include “Unlimited” in the name actually limit high‑speed data to 3GB per day; after that limit the speed drops to 1 Mbps. Travelers looking for higher data volumes can choose RedSim’s fixed data plans instead, such as the Singapore 50GB plan (30‑day validity) or the Singapore 20GB plan (30‑day validity), which offer larger, uncapped data allowances for the duration of the validity period.

RedSim does not provide an eSIM for Singapore that includes a phone number or SMS capability. The available plans from this provider are data‑only, offering mobile data without inherent voice or text messaging services.

Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage through the data connection, but some destinations may restrict or block specific apps or services. It is advisable to confirm that the messaging platforms you rely on are accessible in Singapore before purchasing a plan.

RedSim offers 37 single‑country plans and 17 multi‑country plans specifically for Singapore. Within these offerings, there are 32 daily data‑cap plans and 22 fixed‑data‑cap plans, allowing customers to choose between a set amount of data for the entire validity period or a daily allowance that resets each day. The available plans span a price range of roughly $1.75 to $311.40, provide data caps between 1 GB and 50 GB, and validity periods from 1 to 60 days.
